Analog amplifiers are cataloged by how much current flows during each wave cycle. Measured in degrees, 360º means current flows 100% of the time. The more current, the more inefficient and the more ...

If you have read an amplifier review or looked at the specifications for an amp, the chances are that you have come across a term such as 'Class A/B'. In fact, this is just one of a number of ...

A Class D audio amplifier is basically a switching amplifier or PWM amplifier. There are a number of different classes of amplifiers. We will take a look at the definitions for the main ...

Because pulse modulation output signals are either on or off, Class D amplifiers produce far less heat than analog amplifiers. Reaching efficiencies greater than 90% compared to only 50% for analog, ...

A relatively new technology called the pure digital or Class-D amplifier has been introduced into the audio world. The Class-D architecture allows the input audio signal to stay in its digital format ...

The switching amplifier, or class D amplifier, has risen quickly to prominence in consumer audio applications, from MP3 devices including mobile phone handsets to games consoles, LCD-TVs, and home ...

If you didn’t know better, you might think the phrase “class A amplifier” was a marketing term to help sell amplifiers. But it is, of course, actually a technical description of an amplifier that ...

The Extron XPR Ultra Amplifiers utilize proprietary Class D technologies. Diversifying its product line, the new Extron XPA Ultra Amplifiers offer professionals integrators more channels of ...

Class D audio amplifiers have been increasingly famous in the recent years. This article will present the what’s, why’s and how’s of Class-D audio amplifiers. The article will also present audio ...

As Axiom’s chief R&D engineer Tom Cumberland describes it, a digital amplifier is a “power DAC”, and of course a DAC (Digital-to-Analog Converter) is the basis of all digitally recorded media, whether ...
